arm64: dts: ti: k3-am62x-phyboard-lyra-gpio-fan: Update cooling maps
Rename 'main0_thermal_trip0' to a more descriptive name that
includes 'fan', as the current name is too generic for a fan control
trip point.
Move the fan to a new cooling map to avoid overwriting the passive
trip point used for CPU frequency throttling when this overlay is
enabled. Also, add the fan to the existing cooling map.
